IEEE-841 MotorsCrown TritonTM Series

Experience Combined with Technology

Hyundai Induction Motors use Finite Element Analysis (FEA) and Computer Aided Design

(CAD) methods to develop and produce the most innovative motors from state-of-the-art

and fully automated manufacturing facilities.

Hyundai’s Crown TritonTM cast iron frames greatly improve motor performance by

maximizing heat dissipation.

The use of advanced technology to design and manufacture

electric motors results in a reasonably priced top quality

motor with superior performance characteristics.
